I just run MSE (free) AV and visit the good (paid) porn sites I'm kidding about the porn... but I do run MSE and have never had a problem. I've been doing quite a bit of field work recently at everything from hedge funds to doctor's offices and individuals/small businesses. The biggest problem I find is that people think they need multiple products. Quite often one AV software will try to disable the other AV software on the computer. It's best to have one clean solution and stick with it. Also, do custom installs (not just keep clicking "next"). Don't ever install the toolbars & other crap that they try to force on people. That junk slows down resources and while it isn't an outright virus - it quite often feeds links/pages that lead to viruses.
Just go by PC Magazines top choices: http://www.pcmag.com/article2/0,2817,2372364,00.asp Free anti-virus programs will detect and clean out about 80-90% of the infections. If you want to get up in the high 90s then its best to just pay $50 for a year subscription. The two PC Mag Editors choice antivirus programs are WebRoot and Norton. Norton is the best of the best in detection and cleaning out your system, but it does drag the system and not especially fast. Webroot is almost as good in the detection and cleanout department, but it is very very fast and does not load down the system. I used free antivirus programs like Microsoft Security Essentials, but then found out my email got hacked somehow through spyware. I decided to go with Webroot and since its installation it has detected a lot of viruses. My system gets scanned each and every morning. The scan only takes a few minutes and does not load down the system. If I was running a hedge fund and security was the primary concern then I would go with Norton. However, since I dont run a hedge fund then I go with Webroot as speed and performance of my system is a concern. If you go with either Webroot or Norton then you can go ahead and unload the other firewalls/antivirus programs. Either of those will be better then any free solution and if they cant detect it most probably MSE or other free programs wont be able to either.
why do i need antivirus on a dedicated trading machine? a machine that logs into my broker, and nothing else.
Apple Kidding aside, I like Spyware Doctor and Super Antispyware. Doctor is 30 per year for 3 licenses and Super has a free and pay for version. I use the free one. I'm pleased with the performance of both but Doctor is definitely a resource hog.
